【问题描述】:
我是编写单元测试的新手,我正在尝试使用 testing-library/react 和 jest 为我的 react 应用程序编写单元测试
这里是测试代码“Home.test.js”
import React from 'react';
import {render, cleanup} from '@testing-library/react';
import '@testing-library/jest-dom/extend-expect';
import Home from "../src/Home";
afterEach(cleanup);
describe("Tests for HomePage", function() {
it("should render without throwing an error", function() {
const { homePage } = render(<Home />);
//check something here
});
});
这是我在组件“Home.js”中的代码
import * as React from "react";
import { Panel, Shell, Button } from "@myorg/core";
import { home_icon, new_icon } from "@myorg/icons";
function Home(props) {
const openDialog = React.useCallback(() => {
//do something
});
return (
<Shell.Page breadcrumbs={[t("demo:Home")]}>
<Panel style={{ height: "100%" }}>
<h2>App Header</h2>
<Button onClick={openDialog} variant="primary">
<img src={new_icon} width="20" />
{t("demo:New Asset")}
</Button>
</Panel>
</Shell.Page>
);
}
我在运行“npm run test”时遇到错误
Cannot find module '@myorg/icons' from 'Home.js'
【问题讨论】:
-
你跑
npm i "@myorg/icons"了吗? -
@Clarity 是的,我确实跑了
-
对于遇到此问题的任何其他人,
npm install应该是您做的第一件事。
